wp super cache

I installed wp super cache and my blog went completely blank. I tried to access my account and admin through WordPress.org to deactivate and my user name (MrWrighter) is no longer registered! I no longer have access to anything and I need help. Peter

You are posting to the wrong support forum. This one is only for free hosted WordPress>COM blog issues.

If you don't have a username account at WordPress.ORG click http://wordpress.org/support/ and register one on the top right hand corner of the page that opens, so you can post to the support forums there and receive advice from WordPress.org bloggers.
